But there is no strong evidence to support the idea that one fruit or vegetable is particularly good.

Instead, you should focus on having as wide a variety as possible – that is the best way of getting a range of nutrients.

Fish and cancer

My Weekly claims it is a “fact” that eating fish every other day will reduce your risk of bowel cancer by a third, compared to those who eat it fortnightly.

But it’s just not possible to be this confident.

Our Expert Report looked at the evidence on fish and bowel cancer and found that although the evidence seems to suggest it might reduce risk, this evidence is not strong enough to be confident. It’s what the Report termed as “limited suggestive”.

The media and cancer prevention

It is a real shame My Weekly has printed this article because we know that people are confused about cancer prevention advice and get the impression that scientists are always changing their minds. Actually, the advice has remained similar for over a decade.

The problem is not that the studies My Weekly has mentioned are bad ones.

But single studies are like a piece in a jigsaw puzzle – you need to put them together before they start to give a clear picture on how we can reduce our cancer risk.

These were made by an independent panel of 21 scientists after an analysis of more than 7,000 studies and we are confident they represent the best available advice on preventing cancer through diet, physical activity and weight.

This means the article was a missed opportunity because they could have easily reproduced our 10 Recommendations and given their readers some really useful information.

I have been in touch with the editor of My Weekly about our concerns. She has suggested that in future they may run another piece that looks at our advice.
